At home, let's say you have a gigabit switch connected between two machines. You send 1gbit across the link. Does the power consumption increase appreciably?

The Internet at scale is just that but larger. Perhaps there are 50 switches/routers between you and your destination.
The issue comes about when you have a 10gbit bottleneck and customers want to send 15.
- wbl 7y agoThat's where congestion control works.

I'd very much expect the router to use less power idling than when handling 1gbps - especially that routers tend to look into packets, which is computation, which uses power. Also, if the router does does mode change (e.g. Ethernet on one side, fiber on the other), I'd expect more power usage still when busy.
